7-Piece 3/8" Drive Long Reach Hex Bit Socket Set

Brief Overview

This 7-piece hex bit socket set delivers extended reach capability for jobs where standard sockets fall short. Each socket is precision-machined from hardened chrome-vanadium steel with a matte finish and knurled grip band for secure handling and visibility in the workshop. The set covers H3 through H10 hex sizes at 110mm length, making it ideal for accessing fasteners in recessed or hard-to-reach cavities. For shops requiring broader coverage, consider pairing this with a comprehensive 9-piece hex socket variant or a metric-range long socket set to round out your fastener capabilities.

Key Features

• Hex Bit Sizes: H3, H4, H5, H6, H7, H8, H10 (7 pieces)
• Extended Reach: 110mm length for confined access applications
• 3/8" Square Drive: Compatible with standard 3/8" drive ratchets and torque wrenches
• Material: Chrome-Vanadium (Cr-V) steel with matte finish
• Grip Design: Knurled band on each socket barrel for positive thumb grip

• Size Markings: Stamped/engraved identification on each socket barrel

Why Resellers Choose This Set

Workshop Staple. Long-reach hex sockets solve a recurring customer pain point: accessing fasteners in deep cavities, engine compartments, and precision assembly work where length matters. This set addresses the most common hex sizes (H3–H10), giving your customers a practical, compact solution without forcing them to purchase oversized or specialized tool kits.

Margin-Friendly Format. Bundled in a storage case, this set presents as a premium, gift-ready package—justifying a higher per-unit selling price than individual sockets. The case itself adds perceived value and encourages customer retention.

Repeatable Demand. Hex bit sockets see steady turnover in technical shops, automotive service centers, and machinery assembly operations. The long-reach variant attracts professional buyers who know exactly what they need.

Inventory Efficiency. The curated 7-piece range (H3–H10) covers 80% of common metric and SAE fastener applications without unnecessary duplication. This precision keeps inventory lean while maximizing utility.

Professional Application Context

This set excels in scenarios where standard-length sockets cannot reach:

• Engine Assembly: Accessing hex fasteners on valve covers, intake manifolds, and deep-set sensor plugs.
• Precision Electronics: Working with recessed fasteners in control panels, machinery housings, and equipment frames.
• Machinery Maintenance: Reaching fasteners in confined cavities of industrial equipment.
• Automotive Technical Work: Perfect for specialists handling aftermarket components in tight engine bays.

The H3–H10 range aligns with both metric (3–10 mm) and SAE (0.118"–0.375") fastener standards, making it versatile across mixed-standard workshops.

Closing Advantage

A professional distributor stocks this set because it represents reliable baseline coverage—not exotic, not overstocked, but essential for any shop serious about hex fastener work. The long-reach design positions it as a specialized upgrade to standard socket kits, opening an additional sales channel to customers who've outgrown generalist tool sets.

The matte Cr-V construction with knurled grip bands reflects manufacturing quality that justifies professional-grade pricing. Stock it, and you'll find steady demand from toolroom managers and serious technicians who understand the value of purpose-built access solutions.
